Hello my name is ***** ***** thank you for your question.
Do you have a Volt Meter?
Ok.. Well this is my thoughts. Some you may not like.
First off, I am sure you brought this Alternator from your local Auto Parts store, correct?
I run into this allot. I mean allot.
From what I see when it comes to Alternators brought from Auto Parts stores, they either don't work brand new out of the box, or they only last a year or less. They don't have the quality they use to have. So I normally recommend getting the Alternator from the dealer. That is the only place that seems to see have quality parts. Yes it costs more, but you are doing the Job 1 time.
Now, when you get a After Market Alternator that doesn't charge properly, most auto parts stores will then Bench test them. Of course it always passes the bench test. The reason it passes is cause there is no load on the Alternator. So of course it will pass. When you have it installed in the car, that is when you have a Load on the Alternator. In the car is the best place to test it to see if it's charging properly.
If you are able to get a volt meter I can explain to you a easy test to check the charging system. Do you know anyone that has one?
That is a indication that the Alternator may not be charging properly. When items shut down and stop operating that is a sign of the power being re-directed to try to keep the car running.
If you replaced the Alternator, the Alternator should be able to produce enough charging system voltage to keep the car running even if you have a weak battery.
Well in my opinion, since you got the Alternator from the local auto parts store, I have a feeling that it's not charging properly and that is your issue. To determine this a volt meter is all you need. Do you know anyone that has one?
